| Outline of Final Research Achievements |
We performed the following 3 projects using a monoclonal antibody against folic acid receptor beta (FR-beta) which is expressed in activated macrophages. 1. We found that fluorescent molecular imaging using anti-FR-beta monoclonal antibody could detect the decrease of atherosclerosis mediated by angiotensin II receptor blocker in apolipoprotein E deficient mice. 2. We confirmed that the apolipoprotein (a) overexpressing transgenic CLAWN miniature swine developed fatty streak in aorta on normal diet. We try to perform the molecular imaging using anti-FR-beta monoclonal antibody with microbubbles detected by ultrasound machine on high fat diet. 3. We established a sandwich ELISA assay using anti-FR-beta monoclonal antibody and measured the soluble FR-beta concentration of human serum. The patients with abdominal aortic aneurysms (AAA) showed a higher serum FR-beta level compared with the normal control. In addition, we confirmed the expression of FR-beta in AAA by immunohistochemistry.
